Indeed joema.
That is often the case and is how the sound character of a brand gets started, posted, read and propagated.
In reply to:

It seems more likely (although I don't have any hard data) that an audible difference might exist for tube amps



Obviously we are talking about 2 amps that are at least the same amp design. Tube amps have known MEASURABLE differences to back up the claims of audible reports. Together this is enough proof to say tube amps do sound different than solid state. Yet blind tests and measurements of equal build SS amps have shown there is no sound difference (when comparing the apples to apples situation per joema's post) and for some reason this conclusion is not accepted by self professed audiophiles.
Amazing how selective ppl become when the results do not follow one's beliefs.

This Panasonic 2x6 is touting is a Class H amp, not a Class A/B. That alone makes it directly incomparable to what most ppl own.
Experimental design theory 101.
